T3327G - CK Worldwide Pure Tungsten Green Electrodes 3/32" x 7" (10-Pack)

High-Purity Green Tungsten for Aluminum TIG Welding

The CK Worldwide T3327G Pure Tungsten Electrode (Green) is a premium consumable designed specifically for the TIG welding of aluminum and magnesium alloys. Identified by its distinctive green color code, this electrode is composed of at least 99.5% pure tungsten, making it the standard choice for traditional Alternating Current (AC) welding applications. Unlike alloyed tungsten options, pure tungsten possesses unique thermal properties that allow it to form a clean, balled end when heated. This balling action is critical for maintaining arc stability during AC welding, ensuring a smooth and consistent bead profile on non-ferrous metals. It is the preferred choice for operators using older transformer-based machines that rely on a sine wave output.

Welders utilizing transformer-based constant current power sources will find the T3327G particularly effective. The electrode provides excellent arc stability with both balanced and unbalanced squarewave or sine wave outputs. Because it contains no rare earth oxides, it is strictly a non-radioactive option, eliminating safety concerns associated with thoriated tungsten. However, due to its pure composition, it has a lower current-carrying capacity compared to alloyed counterparts and tends to spit at higher amperages. Therefore, it is best suited for low to medium amperage applications where precision on aluminum or magnesium is required. The lack of oxides means the electrode consumes slightly faster than doped varieties, but the cost-effectiveness and specific performance characteristics make it indispensable for certain applications.

This 10-pack of 3/32" x 7" electrodes ensures you have a reliable supply for your fabrication needs. The 3/32" diameter is a versatile size, capable of handling a wide range of material thicknesses commonly found in automotive, marine, and general repair work. When preparing the electrode, it is important to note that pure tungsten does not require grinding to a sharp point like thoriated or lanthanated types; instead, the natural balling effect provides the necessary geometry for the arc. Whether you are repairing an aluminum boat hull or fabricating magnesium components, the CK T3327G offers the traditional performance characteristics expected by professional fabricators. CK Worldwide ensures that every electrode meets stringent dimensional tolerances for consistent feeding and electrical contact.
